yii2 rbac authmanager getRoles() return empty - php

Question

I'm implementing rbac using yii2. But when i try to get the roles that i previously created i get an empty variable : $authorRole = $auth->getRole('admin');
The rule class, where i put the actual rule logic.
yii/console/controller/UserGroupRule.php
namespace app\rbac;
use Yii;
use yii\rbac\Rule;
/**
* Checks if user group matches
*/
class UserGroupRule extends Rule
{
public $name = 'userGroup';
public function execute($user, $item, $params)
{
if (!Yii::$app->user->isGuest) {
$group = Yii::$app->user->identity->group;
if ($item->name === 'admin') {
return $group == 1;
} elseif ($item->name === 'author') {
return $group == 1 || $group == 2;
}
}
return false;
}
}
Now defining the roles..
yii/console/controller/RbacController.php
namespace console\controllers;
use Yii;
use yii\console\Controller;
class RbacController extends Controller
{
public function actionInit()
{
$auth = Yii::$app->authManager;
$rule = new \app\rbac\UserGroupRule;
$auth->add($rule);
$admin = $auth->createRole('admin');
$admin->ruleName = $rule->name;
$auth->add($admin);
}
}
After this i was able to run ./yii rbac/init to generate the rule files:
console/rbac/items.php
console/rbac/rules.php
This is mostly identical to the documentation
yii/commom/config/main.php
'authManager' => [
'class' => 'yii\rbac\PhpManager',
'defaultRoles' => ['admin', 'author'], // your define roles
],
But in
frontend\models\SignupForm::signup()
I get an empty result when i try to get the admin role :
public function signup()
{
if ($this->validate()) {
$user = new User();
$user->username = $this->username;
$user->email = $this->email;
$user->setPassword($this->password);
$user->generateAuthKey();
$user->save(false);
$auth = Yii::$app->authManager;
$authorRole = $auth->getRole('admin');
$auth->assign($authorRole, $user->getId());
return $user;
}
return null;
}
here is the value of $auth :
yii\rbac\PhpManager#1
(
[itemFile] => '/advanced/frontend/rbac/items.php'
[assignmentFile] => '/advanced/frontend/rbac/assignments.php'
[ruleFile] => '/advanced/frontend/rbac/rules.php'
[*:items] => []
[*:children] => []
[*:assignments] => []
[*:rules] => []
[defaultRoles] => [
0 => 'admin'
1 => 'author'
2 => 'admin'
3 => 'author'
]
[yii\base\Component:_events] => []
[yii\base\Component:_behaviors] => null
)

It's probably because you generate the rbac in "console/rbac/items.php and
console/rbac/rules.php" but your rbac PhpManager is looking this files in advanced/frontend
You could move this files or set the correct paths
'authManager' => [
'class' => 'yii\rbac\PhpManager',
'itemFile' => '#common/rbac/items.php',
'assignmentFile' => '#common/rbac/assignments.php',
'ruleFile' => '#common/rbac/rules.php',
'defaultRoles' => ['admin', 'author'], // your define roles
],
The "#common" is yii2 alias all available aliases listed here: http://www.yiiframework.com/wiki/667/yii-2-list-of-path-aliases-available-with-default-basic-and-advanced-app/
This should help, let me know if there will be still an issue
